Hepatic microcirculation in the anaesthetized rat was observed microscopically with the use of television, the liver being transilluminated by a light guide to provide a cool and bright light source. The study showed that the hexagonal lobular pattern of intrahepatic structure suggested in histological section could also be seen in the trans‐illuminated liver in situ . No intermittent flow was seen in the main sinusoidal channels or in the interlobular portal or central veins, but intermittent flow was observed in some of the anastomosing sinusoids which connected the main sinusoidal channels. There was no evidence of a specific sphincter mechanism in any portion of the sinusoidal bed of the rat liver.
